I have the following questions about assigning HPS pins:
- Do we need to assign HPS pins location in quartos (as I understand the pins location should already be known for each device)
- when using HPS peripheral, what is the meaning of number (0,1,2) in "I/O set 0", "I/O set 1" ... I tried to change between these option and I see no change in the pin selection table.
In the pin assignment the 0,1,2 represent low, medium, high. For example in slew rate, by default, the slew rate is 1 which is fast.
The high slew rate will tend to have faster 0 -> 1 or 1 -> 0.
I hope this this answers your question.
